UNITED STATES CHARLES E. SIPOLE, OF BRGWNFIELD, PENNSYLVANIA.

NONGLARE HEADLIGHT.

Application led April 21, 1925.

It is a'purpose of the present invention to provide, in a headlight, means to reduce the glare of the rays from the headlight, and to accomplish this result it is the aim to arrange a luralityof plies of wire fabric adjacent t e inner face of the plain lens of the headlight, with means centrally of the disks of wire fabric disposed axially with the bulb to cut down the greater part of the central rays. v

Another purpose is to arrange the disks of wire fabric in' diiferent'positions so that the intersecting wires of the fabric may assume different angular positions, ywhich will tend to red-nce the rays emanating from the reflector of the headlight.

Still another purpose is the revision of means for fastening a disk or shield centrally on the wire fabric plies to prevent the same from slipping, said disk or shield acting to cut down the direct cent-ral rays from the bulb of the headlight.

It is to be understood that the particulars herein given are in no way limitative and that, while still keeping within the scope of the invention, any desired modifications of detail and desired proportions may be made in the apparatus according to the circumstances.

The invention comprises further features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is Aa vertical sectional yiew through a conventional form of headli ht, showingy the plurality of plies of wire abric and the disk which reduces the central ras from the bulb. y

igure 2 is a front elevation, showing a portion of the plain lens broken away and each of the plies of wire fabric broken in order to distinguish one from the other, articularly ata point where the central dis is located.

Figure 3 is a sectional view through the several lies of `wire fabric, Showing the central isk as fastened to the intermediate plgf wire fabric. y

ferring to the drawings, 1 designates a casi of an ordinary automobile headlight whic has the conventional form of reflector c 21nd conventional form of bulb 3. The

casing has a flange 4, and a rim 5 is fas` tanedtothel ots 7 of the flange. This Serial No. 24,784.

connection lof theri'm is of the conventional type which is in general use.

The rim retains the lens 8 (which is plain) in position, and ordinarily this lens engages a suitable packing, but in the present case a plurality of plies of wire fabric are interposed between the lens and the packing 9. The plies of wire fabric are designated 10, 11 and 12, the former being next to the lens, the latter being in contact with the packing, whereas the intermediate wire fabric carries a, central shield or disk 13. This oentral shield or disk is of a diamter substantially one-fourth the diameter of the headlight and is positioned in direct axial alignment with the bulb, so as to out down the central rays from the bulb. The shield is provided with a plurality of perforations or apertures 14, not large enough to permit the rays of light to penetrate therethrough but just of sufficient size to receive a fastening wire 15 which fastens the shield to the intermediate wire fabric disk.

It will be noted that these plurality of plies of Wire fabric disks are positioned so that their intersecting wires may assume different angles to each other; that is, the intersecting wires of the outer wire fabric disk may be at an les to the intermediate wire fabric disk, W ile the wires of the innermost wire fabric disk are at angles to the wires of the outer and intermediate plies of wire fabric. 'By this arrangement,

the wires of the several plies act to cut' down or reduce the rays from the reflector of the headlight, enabling a chauffeur of an oncoming automobile to observe readily the roadway Without any inconvenience whatever from -the glare. `The marginal edges of the outer and inner wire fabric lies are connected together, as at 16, simply y bending the various terminals of the intersecting wires in engagement with each oher to insure a lock ]oint between ,the

ies. p The invention having been set forth, what is claimed is 1. In a headlight, the combination with a headlight casing, a lens therefor, and means for fastenin the lensin lace, of a plurality of plies o wire fabric a jacent the inner face of the lens, the intersecting of the wires of each ply being at a different angle to those of the other plies, and a shield of substantially less diameter than the plies of fabric connected centrally tothe plies of fabric for intercepting the central rays from a bulb mounted on the interior of the headlight casin 2. In a eadlight, the combination with a headlight casin and a plain lens therefor, of a plurality o plies of wire :fabric disposed ad'acent the inner face of the lens, a shield o substantially less diameter than the plies of fabric interposed between the innermost ply and an adjacent ply for intercepting the central rays from a bulbmountedA 011 the interior of the casing, and means for fastening the shield to an intermediate ply of Wire fabric.

In testimony whereof he aflixes his signature.
